These products follow the relevant regulations set by NCC, Taiwan & FCC, The U.S.A. 2. It is possible to cause interference between different RF in UHF system. 3. Do not point microphone head direct to speaker to avoid loud hissing noise which may cause damage to your hearing or the loudspeakers of the system. 4. Do not use external force to damage products for a longer lifetime. 5. Do not place or storage products in the environment of high humidity and temperature 6. Please remove batteries for protection of the transmitters when not using transmitters in 7. Do not take the products apart to repair by yourself if any problem occurs. for a long time. a long time. Solution for frequent asked problem Problem Possible cause Microphone and receiver are not on the same channel. No RF signal Microphone is out of range. Microphone or receiver turns off. Microphone is out of battery. Disconnection to channel or noise Signal interference from the certain a environment 9 Possible solution Set the microphone to the same channel as the receiver Check the squelch threshold setting Shorten the distance between microphone and receiving antenna Ensure the correct polarity and turn on the switches. Replace new batteries. Reposition the antennas Reset SQ Set the microphone and receiver to another channel Cautions to the user Notice:
The changes or modifications not expressly approved by the party responsible for compliance could void the users authority to operate the equipment. RF exposure statements IMPORTANT NOTE:
To comply with the FCC RF exposure compliance requirements, no change to the antenna or the device is permitted. Any change to the antenna or the device could result in the device exceeding the RF exposure requirements and void users authority to operate the device. 10
